Lumen is a Bicycle with a Frame that Glows at Night for Added Visibility

A cyclist could wear a bright orange vest, hang lights on their handlebars and attach reflectors on their spokes and their bicycle still won't be as visible at night as this retro-reflective bike. Appropriately dubbed Lumen, the retro-reflective bike may look like an unassuming charcoal-colored bike by day, but at night it glows fully without the help of batteries or switches.

Designed by Mission Bicycle Company, the retro-reflective bike is covered in a special coating from Halo Coatings, which is the same kind of paint found on roads. Design Milk writes, "This coat essentially returns light to its source, instead of bouncing or scattering the light." Safe and stylish, the retro-reflective bike may change the way bicycle designers finish their products.
